Question

I’m trying to use a variable created in local scope without assigning that variable in global. Look what I mean :

<?
function foo(){
    $bar = inside;
}
foo();
echo $bar; // It will give an error that $bar is not assigned
?>

Now you may have understood what I’m trying..? Yes I want to echo that $bar without assigning it in global scope.

Some coding examples are well-honored.

Thanks in Advance

Only possibly way is to use the $GLOBALS super-global (at least without returning it):

function foo(){
  $GLOBALS['bar'] = 'baz';
}

foo();
echo $bar;

Otherwise you’re looking at defining it in global scope first, then specifying you need access to it using global:

$bar = null;

function foo(){
  global $bar;

  $bar = 'baz';
}

foo();
echo $bar;

The better alternative is to use objects where scope remains within the object and you can still retain structure and integrity of code:

class Foo
{
  var $bar = null;

  function Bar()
  {
    $this->bar = 'baz';
  }
}

$foo = new Foo();
$foo->Bar();
echo $foo->bar;
